Introduction

Dimensions of the Human Heart and its Orifices at Term
Human Heart at Term[1]

The ductus arteriosus (ductus Botallo) is a direct connection between the pulmonary trunk and the dorsal aorta. Postnatal closure occurs initially by by smooth muscle contraction and begins at the first breath and is rapid, completed within the first day (about 15 hr after birth). Anatomical closure is much slower occuring by 2–3 weeks after birth (33% of infants), by 2 months (90% of infants) and by 1 year (99% of infants). The adult anatomical remnant of the ductus arteriosus is the ligamentum arteriosum.


The ductus arteriosus, and its corresponding ligament, historically were described as the ductus Botallo, but should this have really been the ductus Aranzio?[2]
